Last year near the end of the year we accidentally scuffed the prop on the ramp while loading. While there was noticeable scuffs and slight bends on the prop, there didn't appear to be serious problems or vibrations, so we didn't have it repaired over the off season. This year, in the short time (~4 hours) we've run her, it seems that there is a bit more vibration than I remember it ever having. Its not like the boat is shaking or anything, but there does seem to be more vibration being transmitted through the boat. Would a bent prop do this, or is this in the drivetrain? How much are new props, and how difficult are they to replace? Is this something better left to professionals?
